My Lenovo Tab got stuck into bootloop, (I deleted a system app by mistake), i thought Wipe Data/Factory Reset should do the trick (recover my phone) which is stock rom by the way, but after reboot (from factory reset) it never finish up booting, it took more than 1 hour and the load bar (of the first boot) still in the middle. (I read somewhere that the first foot take long, depending on the system files, how big and everything), but I'm pretty sure should not take longer than 20 minutes, 30 minutes tops, and I wait even longer but seems the boot just stuck there...
Really need help how to get the phone working again.

About 3-4 months ago I flashed stock ICS into my Galaxy S2 (I did not wipe the cache, which I discover today was a mistake). I noticed a few weeks later that it was a bit unstable, crashing, restarting, etc. I did not care much and just kept using it.
Today it just would not boot, so after 1 hour trying, I managed to keep it alive (using safe mode) long enough to go to setting and have a factory reset.
Then it would not boot again.
From there, I tried several times the factory reset and wipe cache (using volume up + home + power menu). It would sometimes hang on the "installing applications" until several restarts it would eventually go. Then it would hang randomly on startup "s" video, until I managed to get to the welcome screen - which freezes pretty much on the first or second screen (choosing language and date/time).
I flashed I9100GXXLPY_I9100GDBTLP3_DBT and got the same result.
The phone is not rooted, there is no clockwork and I can't even access the phone to put it into debug mode.
Anyone has any more idea of what can be done besides throwing it on the trash? :/
Hey guys,
I just upgraded to Revolution HD 32.0 (coming from 31.0).
Here's what i did.
Boot into recovery.
Clear cache+dalvic-cache.
Install zip from sd-card (select revolution hd 32.0)
Started Aroma installer, left everything pretty much default, just removed some of the samsung junk.
After the install was finished i cleared the cache again and rebooted the device.
It started with the start up logo and after a minute or so "Android upgrading..." with the applications counting.
After that it shows "Finishing boot"
Then nothing, it stays at that for like 5 minutes, then reboots and stays stuck at the samsung logo.
So i decided to boot into recovery, whipe caches and fix permissions and reboot again.
Same thing happened as before.
So i wanted to do a full clean install of the rom, wiping all userdata.
Surprise! Can't get into recovery or download mode anymore.
Took out battery for a few minutes and put it back in.
Still can't access download mode or recovery with vol+menu+pwr...
Does anyone know what's going on, or better, how i can possibly fix this?
I have no idea how to access my device now to make changes...
Thanks a lot!
If you can't get into bootloader with vol down, home and power button then you have a brick, service centre repair required.
Worth trying a USB repair jig to get download before paying for a repair .

Hello.
I have a i9100 smartphone with stock XWLSW firmware. After last change of firmware I did not even root it. So it was all stock without root.
My battery was already in bad condition - from 9 AM till 2-4 PM it gets to 15%.
But anyway.
Yesterday it discharged to 1%, when I plugged charger into the phone. I left it working, and after a while I tried to turn the screen on, but the phone was not responding to power key. It was not turning on the screen, and long hold did not turn the phone on.
I unplugged the charger, took out battery and saw a small wet spot on sticker and on battery (maybe it leaked a bit).
Well, it was not the first priority at the moment, so I just wiped it, and put the battery back, then I turned the phone back ON.
It started, but now I have a boot loop at Samsung Logo. When the battery was still discharged I could hear the discharge signal after logo, and then the logo starts again, and discharge signal again, etc.
I left it in that state for a night with charger plugged in. In the morning - it was in the same condition.
Things I tried:
Removing battery for over 10 minutes, clearing Cache from recovery.
Both recovery and download modes are working.
So the question is - can I restore the phone without Factory reset?
If not - can I somehow backup my data (savegames, etc) before doing factory reset?
I just tried to update the firmware again using ODIN with no luck. It updated successfully, but than again hangs on Samsung Logo.
Rule 1: Don't complain until you haven't tried factory reset.So be a man,and do a full wipe.

What he said. Also, flash a 3 part firmware, which will also wipe your phone & has a funny habit of fixing situations like this.
I was going to do a Factory Reset or flash 3 part firmware, but only after I backup data. That was my main point of creating this thread - how to backup data in this situation.
Anyway, I did install Philz kernel, wiped dalvik cache, cache partition - it helped, but not for long. I saw my desktop, but after few seconds it went into boot loop again. I then did a Custom backup of data only, and did a Factory Reset through recovery.
Now I try to restore data to see what it will give me.
So i have been having pretty much the same problem with some little differences.
First my battery seems OK, no leaking no nothing, but it might just got old as I've got the phone for over 2 years now... Second, my bootloop occurs after full discharge, when i try to turn on the phone afterwards it just gets stuck on Galaxy SII logo, not even the boot, and stays that way no matter how long i wait. Third, at about the last 5-8% my screen starts flickering as if it wasn't getting enough electricity which shouldnt happen too and never happend before 4 months or so.
So lastly I've been getting this bootloop every now and then. Ive got a temporary fix by backing up my phone through recovery then wiping it clean and then restoring. But i just cant figure out why it does that.... I mean wipe helps, but i do restore everything afterwards....
Without restoring the problem still occurs so its not like i restore something deffective in the sw that makes this happen...
The phone is rooted and has a few Xposed modules installed; stock ROM.
I shut the phone down every night. When I wake up and turn it on, every now and again it gets into an infinite boot - not a bootloop (at least not in my understanding). It either stays on the LG logo or the Tmobile logo. Sometimes it boots just fine and quick, sometimes takes a minute longer. Other times I have to hold the Power + Volume Down for a few seconds to reboot it, and it boots fine after that. Yet other times, I have to get into the Factory Reset mode and rebuild the Dalvik cache form within TWRP, after which it boots fine.
The weird thing is that when nothing is changed from the moment it loops to the moment it boots fine; it may only be a reboot away. Granted, I do have (quite) a few things frozen and/or removed in Titanium Backup, but should it affect the boot?
Has anyone experienced anything like that?
Attached are the warnings and errors captured while LiveBoot was running. The lines go really fast, and Nexus 5 shutter isn't capable of going that quick (that's why you can see double lines in certain places). The phone booted after I switched to my swap battery.
Just an update, I restored the earliest Nandroid backup and instead of uninstalling these apps, I froze them in TB. No boot issues so far.
Another update. This morning the problem seems to be back, it was stuck on the T-Mobile logo. Although I can rebuild the cache, it's worse now, because I haven't disabled any LG or system apps since the last restore.
Update to this update: after the T-Mobile logo reboot, it now stuck again on the LG logo and took two 5-minute waits before reboots; it booted fine on the third (essentially, the fourth) reboot upon swapping the battery.
Does anyone else experience this?
